crackling audio on Adobe Premiere Pro CS3

Try deleting your audio peak files. The location is in your preferences.

Hi Stephen
I’m having the same problem. In my case the crackling audio in the export output occurs when I’m exporting from a nested sequence. If I export the same clips from a “basic”, un-nested sequence, the audio is OK.
Have you noticed the same in your case?

Furthermore the crackling audio only occurs in clips where I have applied some audio effects (MultibandCompressor).
Have you noticed the same in your case?

Hi Vincent

1) I can’t find any location information for peak files in the PP’s preference dialog.
Can you tell me more precisely where to find those files or the locatino information?

2) The crackling audio occurs in clips to which I have applied som audio effects (with the MultibandCompressor) in order to enhance the audio in the clips.
Do you know if deleting the peak files will have any effect on the effects that I have applied to the clips? (I don’t want to lose the MultibandCompressor-effects, you know).

Thanx in advance
Hugin

It really shouldn’t be there either way. I usually find that this is due to corrupted audio preview files. I’ve also seen it happen on Quicktime files, and for that there was no solution.

I would at least try to delete those peak files which are under Scratch Disks > Audio Previews. By default, it is in the same folder as your project file, in a subfolder named Media Cache Files > “Project Name”.MACC

………Annnnd inside that folder, you can delete all the .pek files, that will force Premiere to regenerate them.

Cheers,

I deleted those and it generates new files that still have crackle. I can’t figure it out, I might just reinstall.

No, it occurs on all clips right when I capture them.

I had this same issue and I found a fix. Export the audio as a WAV, then bring it into your timeline replacing the other audio. Then, export that as a AVI (or whatever) and it will sound fine. This is something Adobe should probably fix pretty soon, but in the meantime this works fine when working with audio with effects applied.

Lots of answers on the Internet – but Jon’s solution was the only one that worked for me – Thanks

This is an old thread but nevertheless the problem persists in Premiere Pro CC. I also found a plausable cause.
The audio will crackle randomly if the sample rate of the .pek file and the sample rate of the timeline differ.
Halfway through a project I noticed the timeline was set to 44.1 kHz instead of 48 kHz
When I changed it to 48 kHz the random crackling started. Mostly at the start of a clip, must be due to inferior realtime conversion algorithm.
Premiere will try to playback the 44.1 preview (.pek) files while outputting at 48 kHz.
Deleting the .pek files forces premiere to recreate them in the right sample rate and all is fine…
